Holder: President can't use drones on American soil

As the battle over the use of drones heats up, U.S. Attorney General Eric Holder has provided a letter that may take the fight out of some critics.

In a simple letter, Holder informs Sen. Rand Paul that the president may not authorize certain drone strikes on American soil.

Dear Senator Paul:

It has come to my attention that you have now asked an additional question: "Does the President have the authority to use a weaponized drone to kill an American not engaged in combat on American soil?" The answer to that question is no.
